Add a new Block Bindings source, `core/post-data`, which exposes `date` and `modified` fields for now -- reflecting the publish date and the last modified date of the post, respectively. The source could be subsequently extended to include other fields associated with a post object, such as title, featured image, etc. Props bernhard-reiter. Closes #63741. Built from https://develop.svn.wordpress.org/trunk@60539 git-svn-id: http://core.svn.wordpress.org/trunk@59875 1a063a9b-81f0-0310-95a4-ce76da25c4cd
